Hantaan virus Howang strain which isolated from the blood of severe case of Korean hemorrhagic fever is more virulent than HTN 76/118 and showed different RFLP from partial PCR amplifed M genome segment to established Hantaan serotype viruses. We have determined the nucleotide sequence of the M and S genome segments and compared to HTN 76/118. The M and S segment of Howang strain has 3615 and 1696 nucleotides long, respectively. The M segment sequence of Howang strain is one mucleotide shorter than HTN 76/118. The sequence data of Howang strain shows 93.5% homology to HTN 76/118. One long open reading frame, which strats from 41nt. to 3448nt. of the M segment and from 37nt. to 1326nt. of the S segment, exist to on complementary sense of the virus genome. There are no significant difference between HTN 76/118 and Howang strain on hydrophobicity of deduced polypeptides, but has slight difference on secondary structure.

Hantaan virus (HTNV), the etiologic agent of hemorrhagic fever with renal syndrome (HFRS), belongs to the genus Hantavirus, and has three single negative stranded RNA genome segments. HTNV strain Howang isolated from the blood of severe case of Korean HFRS is more virulent than HTNV 76/118 and the M and S genome segments' nucleotide sequence of Howang strain showed 93.5% and 94% homology to each segment of HTNV 76/118. We have obtained 6533 nucleotides long sequence of the L genome segment of Howang strain using reverse transcriptase in conjunction with PCR amplification and compared to other hantaviruses. The messenger sense of the L segment contains one long single long open reading frame of 2151 amino acids, which encodes a deduced RNA dependent RNA polymerase of 246.4 kDa caculated molecular weight protein. The nucleotide sequence of the L segment of Howang strain shows 93%, 74%, 66%, 65% homology to HTNV 76/118, Seoul virus 80/39, Puumala virus $H{\ddot{a}}lln{\ddot{a}}s$ B1 and Sin Nombre virus, respectively. The amino acid sequence of the L segment of Howang strain shows 99%, 85%, 68%, 68% homology to HTNV 76/118, Seoul virus 80/39, Puumala virus $H{\ddot{a}}lln{\ddot{a}}s$ B1 and Sin Nombre virus, respectively.
